Full details

The Betley Butterfly Bathroom Mortice Lock is an essential hardware choice for homeowners and professionals looking to secure bathroom doors with a reliable, thumb-turn compatible mechanism. It is ideal for those who value privacy and ease of use, featuring a versatile reversible latch that simplifies installation on both left- and right-handed doors. While this lock offers robust functionality and a clean aesthetic, users should note that the 57mm backset requires specific door measurements to ensure it fits existing mortice cavities without requiring extensive modifications.

FAQs

Is this lock suitable for exterior doors?

No, this is a bathroom mortice sashlock designed specifically for internal privacy use and should not be used for main exterior security.

Can I use this on a door that opens to the left?

Yes, the Betley Butterfly lock features a reversible latch, making it suitable for both left-hand and right-hand door orientations.

What does a 57mm backset mean?

The backset is the distance from the edge of the door to the center of the handle spindle hole. You must ensure your door is compatible with this 57mm measurement.

Are the fixing screws included?

Yes, the package includes the mortice sashlock, faceplate, striking plate, and all necessary screws for installation.

Will this fit standard bathroom thumb-turns?

Yes, it is designed with standard 44mm centres to accommodate common bathroom thumb-turn and release sets.

Troubleshooting

The latch does not close smoothly against the striking plate.

Adjust the position of the striking plate on the door frame to ensure the latch aligns perfectly with the aperture.

The door handle feels loose after installation.

Check that the bolt-through screws are tightened securely and that the door furniture is correctly seated against the lock case.

The lock is difficult to turn.

Ensure the mortice cavity is deep enough and free of wood debris that might be pressing against the side of the lock case.

Setup, Compatibility & Care

To install this lock, ensure your door has a cavity that accommodates the 108mm by 65mm case. Always verify that your door thickness allows for the 57mm backset to be centered correctly before cutting the mortice.

Use a template to mark the mortice depth and the faceplate recess.
Insert the lock case into the cavity and secure it using the provided screws.
Align the striking plate on the door frame so that the latch engages smoothly.
Secure the faceplate for a finished, professional appearance.

For care, wipe the exposed silver faceplate with a damp, soft cloth to remove dust or fingerprints. Avoid harsh chemical cleaners, as these can strip the protective finish over time.
